エツジベルトの製造方法およびその成形型に関するもの
である。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for manufacturing a low edge belt and a mold used in the manufacturing method, and specifically relates to an arched dot in which the back surface of the belt is arcuate. The present invention relates to a method for manufacturing a type of low edge belt and a mold thereof.
（従来波！り
従来、動力伝動用Ｖベルトの形状はその断面が逆台形状
であり、上面は水平状のものが広く利用されていた。(Conventional wave!) Conventionally, V-belts for power transmission have had an inverted trapezoidal cross section and a horizontal upper surface, which has been widely used.
しかし、上面が水平のＶベルトは高負荷の動力伝動を行
なった時ベルトがブーり溝の中に落ち込む座屈現象を起
こすことがあった。However, when a V-belt with a horizontal top surface performs power transmission under a high load, a buckling phenomenon occurs in which the belt falls into the boob groove.
そこで、ベルトの座屈強度を向上させる方策としてベル
トの上面が弧形であるアーチトドツブタイプのＶベルト

通常のローエツジベルトと同一手段によりベルトスリー
ブを形成し、更に該スリーブを断面Ｖ型に切断するもの
である。Therefore, as a measure to improve the buckling strength of the belt, an arched dowel type V-belt in which the upper surface of the belt is arcuate was invented, and the present applicant also disclosed a means for manufacturing an arched dot type belt for a low edge belt. (Japanese Patent Publication No. 51-44030). Special Public Service 51-4403
The method for manufacturing a low edge belt disclosed by the applicant in No. 0 is to form a belt sleeve by the same means as a normal low edge belt using a mold having a convex waveform in the axial direction, and further to It is cut into a V-shaped cross section.
（発明が解決しようとする課題→
しかし、前記ローエツジベルトの製造方法は、ベルト上

い。(Problems to be Solved by the Invention→ However, the method for manufacturing the low edge belt has disadvantages in that the arc shape of the upper surface of the belt is not sufficiently formed and it is difficult to remove the belt from the mold. That is, in the conventional manufacturing method, the cushion layer side of the belt sleeve is pressed against the convex shape of a mold to form an arc shape on the cushion layer, and as the cushion layer is shaped, an arc shape is formed on the upper surface of the belt. Therefore, it is difficult to form a clear arc shape on the top surface.
また、上面の弧形な明確にするため成形型凹凸は大形の
ものを採用せざるを得す、膜形時にベルトクツション層
が該凹凸と嵌合しベルトの取り出しが困難であった。In addition, in order to make the upper surface clearly arched, it is necessary to use a mold with large projections and depressions, and when the belt is in the membrane shape, the belt cushion layer fits into the projections and depressions, making it difficult to remove the belt.
そこで、本発明は従来技術のかかる欠点に着目し、アー
